Safe treatment with somatostatin analogues in a woman with acromegaly whilst pregnant and lactating.

Context: Pregnancy in acromegaly is rare, there have been few case reports and series published to date. Also breastfeeding under acromegaly treatment is extremely rare. The late diagnosis of pregnancy in acromegaly will sometimes dictate the treatment and management of the patient.

Material and method: We present a 32-year-old woman with acromegaly, a late diagnosed pregnancy and a completed fetal organogenesis. Due to the gestation time and bothersome headaches accompanying a pituitary macroadenoma, we decided to continue long lasting somatostatin analogues treatment but with increased injection intervals of 6 weeks. We also continued this treatment during 12 months of breastfeeding.

Results: Our treatment did not cause any complication of premature birth or any health problems with the newborn baby. The child has since developed normally up to the age of 5.

Conclusion: The course of acromegaly disease and the time of pregnancy diagnosis may prompt suitable drug and treatment regimes. We administered effective and safe somatostatin analogues treatment during gestation and breastfeeding which was safe for both mother and baby.
